MacBook Air 2016 Rumors: Specs Include Touch ID, Skylake Processor

But the team behind it has been working hard to make it much better with many under-the-hood improvements and an important new feature — iPad Pro support. After purchasing the iOS app for $9.99 and installing the companion app, you just need to plug your iPad using a Lightning cable and launch the two apps. The app’s secret sauce is that it uses your iPad cable — you get 60 frames per second without any lag, and it’s much more reliable than using a Wi-Fi network.

While I didn’t actually try it with an iPad Pro, if you have a 13-inch MacBook Pro, you can double the size of your screen real estate with an iPad Pro. I asked Duet Display whether Duet Display was taking advantage of the iPad Pro’s new Lightning port — the port now supports USB 3.0 transfer speeds.
